THE MALE GENITAL OBGANS. 871 COMPARISON OP THE GENITAL ORGANS pF MAN WITH THOSE OF ANIMALS. Coverings of the testicles.—The scrotum, dartos, tunica erythryoidea, nr.d tunica vaginalis h;ive the same org.inisation as in Solipeds. The scrotum is rich in sebaceous glunds, and the tunica vagimdis is separated by a serous layer from the peritoneal cavity. 'Jesticles.—Tliese are ovoid, and situated in an oblique direction downwards and inwards ; their largest curvature is forwards. The epididymis oti'ers the same arrangement as already noticed, except that the vns deferens, in being detached from the globus minur, is bent .omewhat suddenly to reach the abdominal cavity. There are several diverticuli annexed to the epididymis, named the pediculated hydatid of Morgagni, non-jediculated hydatid uherrant vessels, anl roipus innominatum of Giraldes. Fie;. 406.

SECTION OF PELVIS TO THE LEFT OF THE MEDIAN LINE AT THE PUHES, AND THROUGH THE MIDDLE OF THE SACRUM. 1, Section of left pubic bone; 2, Peritoneum on bladder ; 3, Left crus penis ; 4, Pelvic fascia forming anterior ligaments of bladder; 5, Part of accelerator urinse ; 6, Posterior layer of triangular ligament forming the capsule of the prostate; 7, Anterior layer of triangular ligament; Between 6 and 7 are seen the membranous urethra, deep muscles of urethra (insertion), and Cowper's glanJ of the left side; 8, Vas deferens; 9, Bulb of urethra; 10, Rectum; 11, Cut edges of accelerator urinae and transversus perinsei; 12, Left ureter; 13, Reflec- tion of deep layer of superficial fascia round transversus perinrei; 14, Left vesicula seminalis; 15, Cut edge of levator ani; 16, Rectum; 17, Prostate gland. The hydatid of Morgagni is a little projection at the head of the epididymis, filled with a serous fluid which is never mixed with tlie semen. The non-pedicuhited hydatid is a small white mass which rises from tlie testicle Ht some distance from the globus mnjor ; it has a cavity that communicates with the duct of the epididymis. The aherrant vessels are fine flexuous ducts given off from the globus minor, and soon terminate in a cid-de- sac. The corpus innominatum of Giraldes is a small mass of ramifying tubes included in the connective tissue uniting the globus miijor to the testicle. All these appendages of the testicle or eindidymis, are the remains of the WolfSan body. Vas deferens.—This is not united to its fellow by a peritoneal fold; it is slightly dilated on arriviu^^ at tbe neck of the bladder, as in tlie Horse. The vesicular seminales are eloneated, and lobubite'l on their surface, as in Euminants. Urethra.—This canal has a fixed and a free portion : the first is slightly inclined downwards and forwards; the second is suddenly intlected, and, with the preceding, forms the prepubic angle, which disappears with erection. Its diameter increnses a little at tiie bidb, and again at the meatus, to form the fossa navicular is. Its erectile envelope forms a considerable enlargement at its commencement—the bulb, ami this is covered, as in the Ox, by the accelerator urinse; it also composes another, the glans, that
